Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU69943
Risk: Low
CVSSv3.1: 5.6 [CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-2347
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows an attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error in the U-Boot DFU implementation when processing download setup packets. An attacker with physical access to device can send a USB DFU download setup packet with a `wLength` greater than 4096 bytes, trigger a heap-based buffer overflow and execute arbitrary code on the system.
Update the affected package u-boot-nezha to the latest version.
Vulnerable software versionsUbuntu: 22.04 - 23.04
u-boot-nezha (Ubuntu package): before 2022.10-1089-g528ae9bc6c-0ubuntu1.23.04.2
External linkshttp://ubuntu.com/security/notices/USN-6523-1
Q & A
Can this vulnerability be exploited remotely?
No. The attacker should have physical access to the system in order to successfully exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Buffer overflow
EUVDB-ID: #VU64137
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-30552
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the implementation of IP Packet Defragmentation. A remote attacker on the local network can trigger memory corruption and cause a denial of service condition on the target system.
MitigationUpdate the affected package u-boot-nezha to the latest version.
Vulnerable software versionsUbuntu: 22.04 - 23.04
u-boot-nezha (Ubuntu package): before 2022.10-1089-g528ae9bc6c-0ubuntu1.23.04.2

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
3) Out-of-bounds write
EUVDB-ID: #VU64139
Risk: Medium
CVSSv3.1: 8.3 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-30790
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the implementation ofIP Packet Defragmentation. A remote attacker on the local netwotk can trigger out-of-bounds write and execute arbitrary code on the target system.
MitigationUpdate the affected package u-boot-nezha to the latest version.
